The modular CO 2 transmitter EE870 consists of following components: EE871 interchangeable CO 2 probe with E2 digital output. For technical data please see EE871 data sheet and operation manual (www.epluse.com/ee871) For readjustment of EE871 please see data sheet and operation manual EE-PCS Product Configuration Software (www.epluse.com/ee-pcs) HA011014 converter board: The converter board supplies the EE871 CO 2 probe and converts its digital output signal into analogue outputs and Modbus RTU digital interface. The measured data is available simultaneously on the analogue outputs and on the Modbus interface. Technical data, setup and operations instructions for HA011014 are detailed in this document. Connecting cable between EE871 CO 2 probe and HA011014. EE870 scope of supply includes one of the following cables, as ordered: HA010809... 1 m length HA010810... 2 m length HA010811... 5 m length HA010812... 10 m length. 3
IMPORTANT NOTES Connecting the supply voltage to the modbus terminals may destroy the device. The HA011014 converter board is supplied as a component and must be installed in accordance with the valid ESD guidelines and properly protected against enviromental influences. Probe Sensing head Filter cap CO 2 Sensing cell The device shall not be exposed to extreme mechanical stress. The sensing head of the probe and mostly the sensing cell might not be exposed to any mechanical stress. The probe must be operated with the filter cap on at all times. Do not touch the sensing cell or electronics inside the sensing head. A long response time indicates a dirty filter cap, as it might happen in polluted applications. Do not attempt to clean the filter cap; it would only cause its clogging. Replace the filter cap by an E+E original one, order no. HA010116. While replacing the filter cap take utmost care to not touch the sensing cell and the electronics. This device is not appropriate for safety, emergency stop or other critical applications where device malfunction or failure could cause injury to human beings.
